SELF-DIAGNOSTIC SYSTEM

Note. Before performing self-diagnostics, perform TROUBLE SHOOTING .

Connect New Generation Star (NGS) tester to Data Link Connector (DLC), located under center of instrument panel. Using NGS tester, perform data link diagnostics test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - LS article. If NGS tester responds with CKT914, CKT915 or CKT70=ALL ECUS NO RESP/NOT EQUIP, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - LS article. If NGS tester displays NO RESP/NOT EQUIP for Front Electronic Module (FEM), perform TEST A: NO COMMUNICATION WITH FRONT ELECTRONIC MODULE (FEM) under SYSTEM TESTS. If NGS tester displays NO RESP/NOT EQUIP for Rear Electronic Module (REM), perform TEST B: NO COMMUNICATIONS WITH REAR ELECTRONIC MODULE (REM) under SYSTEM TESTS. If NGS tester displays NO RESP/NOT EQUIP for Driver's Door Module (DDM), perform TEST C: NO COMMUNICATION WITH DRIVER'S DOOR MODULE (DDM) under SYSTEM TESTS.

If NGS tester responds with SYSTEM PASSED, retrieve and record continuous DTCs. Erase continuous DTCs. Using NGS tester, perform FEM, REM and DDM self-test(s). See MODULE COMMUNICATIONS NETWORK - LS article. Perform appropriate test in accordance with DTC retrieved. See DRIVER'S DOOR MODULE DTC INDEX , FRONT ELECTRONIC MODULE DTC INDEX and/or REAR ELECTRONIC MODULE DTC INDEX table(s). Codes listed in these tables are only for testing covered in this article.
